By the mixing of sodium sulfide and sodium molybdate within a suitable ph range , molybdenum trisulfide particles were obtained as precipitation substance 在一定酸性的条件下将硫化钠和钼酸钠的水溶液进行混合与反应，生成棕色三硫化钼膏状沉淀。
2.
Then the molybdenum disulfide nanoparticles which size was in the range of 20 - 30 nm were prepared by the desulfuration of molybdenum trisulfide if taking hydrogen as a protection atmosphere at some temperature . the mos2 nanoparticles were then characterized by x - ray diffraction and transmission electron microscope . the mos2 nanoparticles and commercial common mos2 particles ( c . a 将干燥后的三硫化钼粉末在氢气保护气氛条件下，加热脱硫得到粒径在20 30nm之间的纳米二硫化钼颗粒，用x射线衍射仪( xrd )和透射电子显微镜( tem )对二硫化钼纳米颗粒进行了表征。
